Submersible Vs. External Aquarium Lights

When it comes to aquarium lights, you have two main choices: submersible or external. Submersible lights are designed to be placed directly into your tank, while external lights are placed outside. Both have their own pros and cons that you should consider before making a purchase.

Submersible lights are a great choice if you want to create a specific mood or effect in your tank. For example, submersible lights can be used to mimic the gradual sunrise and sunset.

They are also a good choice if you have a smaller tank, as they take up less space. However, submersible lights may not be as bright as external ones, so you can’t grow high-light demanding plants using submersible lights.

External lights are a good choice if you want to brighten up your tank & at the same time, own a planted tank with varieties of plants. However, they are also more expensive than submersible lights, and they usually need to hang from the top.

However, external lights can be more challenging to install, and they may not be as durable; under exposure to water, they can be damaged. But if you want to grow corals or plants, I would recommend going for external lights.

On the other hand, if you want to enhance fish color and grow only low light plants, you can go for submersible light.

Now that you know the pros and cons of each type of light, you can decide which one is best for your aquarium.

Both types of lights have their pros and cons, so it really depends on your needs as to which one you should choose. It really all comes down to what you want to achieve with your aquarium and what will best suit your fish and plants.
